Earlier quoted context omitted.
I just searched "Firefox" in the app store. The top result is Google Chrome with an Ad indicator (Google paid for higher placement). Second is Firefox.
Sometimes it's good to live in a region that no one cares about. I just searched for Firefox in the Android Play Store application, there were no ads, and the first result was Firefox. I also don't get any ads in American and UK podcasts for the same reason (except for those read by the host, but there are few of those and they're easy to ignore).
Does anyone publish a scorecard of search results vs Google region settings?
